KETRON PEEK-CLASSIX LSG white stock shapes are produced from Invibio PEEK-CLASSIX White resin. This material exhibits a unique combination of mechanical properties, temperature and chemical resistance. The composition of the Invibio PEEK-CLASSIX White resin complies with the regulations that apply in the Member States of the European Union (Directive 2002/72/EC, as amended) and in the United States of America (FDA) for plastic materials and articles intended to come into contact with foodstuffs. KETRON PEEK-CLASSIX LSG stock shapes have also been successfully type tested for their compliance with both United States Pharmacopeia (USP) and ISO 10993-1 guideline requirements for Biocompatibility Testing of Materials, and they come with full traceability from resin to stock shape. These features, added to an excellent sterilizability by means of steam, dry heat, ethylene oxide, plasma and gamma irradiation, make KETRON PEEK-CLASSIX LSG stock shapes very suitable for applications in the medical, pharmaceutical and biotechnology markets.

According to method 1 of ISO 62 and done on discs 50 x 3 mm. Only for short time exposure (a few hours) in applications where no or only a very low load is applied to the material. Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength of about 50% as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes place and causes a reduction in properties. Note, however, that the maximum allowable service temperature depends in many cases essentially on the duration and the magnitude of the mechanical stresses to which the material is subjected. Impact strength decreasing with decreasing temperature, the minimum allowable service temperature is practically mainly determined by the extent to which the material is subjected to impact. The value given here is based on unfavourable impact conditions and may consequently not be considered as being the absolute practical limit. These ratings - derived from raw material supplier data and other publications - are not intended to reflect hazards presented by the materials under actual fire conditions. There is no UL-yellow card available for KETRON PEEK-CLASSIX LSG white stock shapes. The figures given for the mechanical properties are average values of tests run on test specimens machined out of rod Ø 50 mm. Unless otherwise specified, the test specimens were taken from the mid between center and outside diameter with their largest size taken in axial direction (parallel to the extrusion direction). Test specimens: Type 1 B Test speed: 50 mm/min (chosen acc. to ISO 10350-1 as a function of the ductile behaviour of the material) Test speed: 1 mm/min Test specimens: cylinders 8 x 16 mm Test specimens: bars 4 x 10 x 80 mm Test speed: 2 mm/min Pendulum used: 25 J Measured on 10 mm thick disks Ø 50 mm, mid between center and outside diameter. © 2005 Copyright Quadrant AG ­ Issue date: December 1, 2005 This table is a valuable help in the choice of a material. The data listed here fall within the normal range of product properties.
